Multi-Screen GUI Color Guidance for Accurate Key Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing apparatuses face issues with operability, as users unfamiliar with operations may mistakenly operate unintended keys or hesitate, leading to inefficiencies.
Innovation Solution
The apparatus includes a display with operation guidance portions colored in a first color, featuring operation keys of different types based on functionality, with transition keys highlighted in the first color when conditions are met, guiding users intuitively through multiple operation screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation keys are displayed on each operation screen, then the service functionality is comprehensive, but users unfamiliar with operations may mistakenly operate unintended keys
Solution Approach 1:
The patent applies local quality by coloring only the guidance target operation key in a different color (first color) while keeping other keys in the second color. This creates a localized visual distinction that guides users' attention to the correct key without changing the overall interface structure or removing other functional keys, thus maintaining comprehensive service functionality while improving operation accuracy.
2Adaptability or versatility
If multiple operation keys are displayed on each operation screen, then the service functionality is comprehensive, but users may hesitate and take a long time on the operation
Solution Approach 1:
The patent uses color changes to visually distinguish the guidance target operation key from other keys. By displaying the guidance target key in a different color (first color) versus the second color for other keys, the system quickly directs user attention to the correct operation, reducing hesitation and operation time while maintaining all necessary functional keys on the screen.
3Device complexity
If all operation keys are displayed with the same appearance, then the interface is simple, but users cannot easily identify which key to operate
Solution Approach 1:
The patent maintains interface simplicity by keeping all keys with the basic second color appearance, while applying the first color only to the guidance target key. This localized differentiation allows users to easily identify which key to operate without adding complex visual elements or changing the overall interface structure, thus resolving the contradiction between interface simplicity and key identification ease.
4Loss of information
If operation guidance is provided through text only, then the information is clear, but users may still operate unintended keys due to lack of visual emphasis
Solution Approach 1:
The patent merges text-based operation guidance with visual color coding. The display controller displays both the operation guidance text and colors the guidance target operation key in the first color. This combination of textual information and visual emphasis reinforces the correct operation, preventing users from operating unintended keys while maintaining clear guidance information.

AI summary
The information processing apparatus includes a display. The information processing apparatus accepts user operations via a GUI (graphical user interface) displayed on the display. The operation screen is displayed on the display. On the operation screen, an operation guidance portion, including a message for providing operation guidance to the user, and a plurality of operation keys for accepting user operations are displayed. A part of the operation guidance portion is colored in a first color, the operation keys which are the first type of operation key are colored in the first color, and the operation keys which are the second type of operation key are not colored in the first color.
